Comment 6 for bug 746589

Hi Michael,

We use python-apt to access the Cache and check if desktopcouch-ubuntuone (and some other couchdb packages) are installed. We need to do so to enable some replication services, and those packages are not shipped in the CD anymore (so is very likely they are not present).

We could catch the exception, but if the underlying layer will fail without going over the sources that does have read perm, there isn't much we can do. The apt guys suggest that we shouldn't be setting 640 as file mode nor be adding passwords in the sources files (see bug #746625).
